I was reading an article about, among other things, how big Tobacco worked to plant doubt into people's minds over research ion the health risks of smoking.
This was the closing sentence:
"You really need to be teaching third-, fourth-, fifth-, sixth-graders that some people lie. And why do they lie? Because some people are greedy."
It resonated with me for obvious reasons! I think that simple summary really explains the behavior of many waywards. But I for one was never taught that this was part of life, so the idea of teaching this to kids also resonated!
